I was installing everything with relative ease so I left my computer unattended to go eat some food. When I came back, the computer had restarted and sounded fine except there was no video output. (I aIso couldn't hear the hard drive spinning), thinking this was normal, let it sit for about 3 hours before I got suspicious. So I tried all of the availiable video ports (except displayport) and none of them had a signal. I let it sit for about 2 more hours, still, nothing. So I tried turning it of and back on again. Still, nothing. Any help is much appreciated.
